I had originally created a safe `set_locale()` wrapper and clippy-disallowed
`libc::setlocale()` but almost all our uses of `libc::setlocale()` are in a loop
where it makes much more sense to just obtain the lock outright then call
`setlocale()` repeatedly rather than lock it in the wrapper function each time.
No need to use cfg_attr and have to worry about syncing the preconditions for
the cfg_attr with the preconditions for where `slice_contains_slice()` is used
in the codebase, just mark it as `allow(unused)` with a comment.
pcre2-sys includes a vendored copy of PCRE2, which allows for
statically-linked PCRE2. Hook this up to the CMake build variable, and
remove the C++ integration for PCRE2.
They are probably not terribly useful for us but let's see what happens.
Unfortunately cargo does not properly forward the combination of "RUSTFLAGS"
and "--target" that is currently required to build with ASan [1]. Hence doctests
will fail to link on ASan builds. Let's disable doctests when ASan is active.

Use Rust for executables
Drops the C++ entry points and restructures the Rust package into a
library and three binary crates.
Renames the fish-rust package to fish.
At least on Ubuntu, "fish_indent" is built before "fish".
Make sure export CURSES_LIBRARY_LIST to all binaries to make sure
that "cached-curses-libnames" is populated.

With the next commit, if I run
docker/docker_run_tests.sh --shell-after docker/jammy-asan-clang.Dockerfile
I get this in test_string.fish and test_git.fish:

Strangely there is no tparm in the call stack. It does not seem to happen
in CI.
This makes "ninja test" write only to the build directory, not to the source
tree. This enables our docker script which mounts the source as read-only.
Some tests create files like "./test/test-home". Traditionally the did so
in the first parent directory that contained tests/test.fish; so either a
build directory or the root.
The new rust version always changes directory to the root. This blows up
when running with our docker/ files, which mount the source as read-only.
Fix this by always changing directory to the build directory.
In future we could extend this to not chdir if FISH_BUILD_DIR was not
specified, to match traditional behavior. No strong opinions here.
Update the pydoctheme.css file to add support for print media.
The code was adapted from the existing support for screens that are less than
700px wide, with the following changes:
- Remove the documents and sections index
- Remove the quick search
- Remove dead CSS code
Additionally, add section numbers and ensure that code blocks are never split
across multiple pages.
